Bone lid surgery (BLS) is minimally invasive surgery that removes the cortical bone and returns it to original position after removing lesions. However, jawbone lesions are completely covered with cortical bone, and it can be difficult to accurately determine the lesion position from the outside.
A 24-year-old Japanese woman, identified as having an impacted maxillary canine, was referred to our department. Periapical radiolucent lesion, with lateral incisor root absorption by canine compression, was confirmed.
The diagnosis was incisor root absorption due to an impacted canine.
As a potential solution, we performed navigation-assisted BLS.
Using navigation, we could confirm the state of impacted tooth under the covered bone. We could establish reliable bone cutting and the removed cortical bone was successfully returned to the presurgical position.
TAKE-AWAY LESSONS: Navigation-assisted BLS for the removal of impacted teeth may increase surgical accuracy and minimize invasion.
骨盖手术（BLS）是一种微创手术，它切除皮质骨并在切除病变后将其恢复到原始位置。然而，颌骨病变完全被皮质骨覆盖，从外部很难准确确定病变位置。
一名24岁的日本女性，被诊断为上颌尖牙阻生，转诊至我科。确认存在根尖透射性病变，侧切牙根因尖牙压迫而吸收。
诊断为阻生尖牙导致的切牙根吸收。
作为一种潜在的解决方案，我们进行了导航辅助BLS。
通过导航，我们可以确认被覆盖骨下阻生牙的状态。我们能够进行可靠的骨切割，并且切除的皮质骨成功恢复到术前位置。
导航辅助BLS用于拔除阻生牙可能会提高手术准确性并减少侵袭。
